In order to ensure high-quality wire and effectively control the cost of mold use, attention should be paid to the following aspects:
To ensure the smooth operation of the wire drawing die equipment; the wire drawing drums and wire guide wheels should be smooth and flexible, and their runout tolerances should be strictly controlled. If worn grooves are found on the drum and guide wheels, they should be repaired in time.
Good lubrication conditions are an important condition to ensure the surface quality of the wire and extend the life of the mold. Always check the lubrication strength index, remove copper powder and impurities in the lubricating oil, so as not to pollute the equipment and die holes. If the lubrication fails, the lubrication system must be replaced and cleaned in time.
Reasonable die matching is a key element to ensure the surface quality of the wire, control the exact and consistent dimensions, reduce the wear of the wire drawing drum, and reduce the operating load of the equipment. For the sliding wire drawing machine, it is necessary to be familiar with the mechanical elongation of the equipment, and to select the sliding coefficient reasonably, which is the first step of mold matching.
The pass type of the mold is selected according to the material of the wire to be drawn and the reduction rate of each drawing. Generally speaking, the harder the drawn wire, the smaller the compression angle of the mold and the longer the sizing area; and vice versa. The reduction rate of each drawing is also closely related to the compression angle of the corresponding die. The compression angle should be adjusted appropriately according to the reduction rate.
